Training Homework Answers



 



If you scheduled the training with our team, you should have received an email explaining how to get access to 4 server machines of our training environment. In this page, we are going to refer to them as: bee-1-1, bee-1-2, bee-1-3 and bee-1-4.

Homework 1

Dedicated Servers Installation


Install BeeGFS on these nodes. Initially, use dedicated servers, with each machine running a different type of service.
  1. Firstly, switch to the root user, and change its password to the same password used by user training, to make the next steps easier. Then, update all packages installed on the machines, to make sure the system is up-to-date.
    $ sudo su - $ passwd $ yum update
  2. Execute command to list the block devices available in all machines.
    $ lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT vda 252:0 0 20G 0 disk ├─vda1 252:1 0 1G 0 part /boot └─vda2 252:2 0 19G 0 part ├─centos-root 253:0 0 17G 0 lvm / └─centos-swap 253:1 0 2G 0 lvm [SWAP] vdb 252:16 0 20G 0 disk vdc 252:32 0 20G 0 disk
  3. Format the partitions vdb as ext4 and vdc as XFS on all machines.
    $ mkfs.ext4 -i 2048 -I 512 -J size=400 -Odir_index,filetype /dev/vdb $ mkfs.xfs -l version=2 -isize=512 /dev/vdc
  4. Create directories for the targets’ mountpoints on all machines, as follows.
    $ mkdir /mnt/vdb $ mkdir /mnt/vdc
  5. Configure the partitions to be mounted at boot time by adding the following lines to .
    $ vi /etc/fstab ... /dev/vdb /mnt/vdb ext4 noatime,nodiratime,defaults 0 1 /dev/vdc /mnt/vdc xfs noatime,nodiratime,logbufs=8,logbsize=256k,allocsize=131072k,defaults 0 1
  6. Now, mount the partitions by running the commands below.
    $ mount /mnt/vdb $ mount /mnt/vdc
  7. Execute the command below on all machines to disable the firewall.
    $ systemctl stop firewalld $ systemctl disable firewalld
  8. Set option in file in all nodes and reboot the machines to make the setting effective. When the machines are back, log in and check if the partitions were mounted.
    $ vi /etc/selinux/config SELINUX=disabled $ reboot ... $ ssh bee-1-1 $ mount ... /dev/vda1 on /boot type xfs (rw,relatime,attr2,inode64,noquota) /dev/vdb on /mnt/vdb type ext4 (rw,noatime,nodiratime,data=ordered)
  9. Install the BeeGFS repository file in all nodes, as follows.
    $ sudo su - $ yum install wget $ wget -O /etc/yum.repos.d/beegfs-rhel7.repo https://www.beegfs.io/release/latest-stable/dists/beegfs-rhel7.repo
  10. Install and start the BeeGFS services, following the installation guide.
    bee-1-1$ yum install beegfs-mgmtd bee-1-1$ /opt/beegfs/sbin/beegfs-setup-mgmtd -p /mnt/vdb/mgmtd bee-1-1$ /etc/init.d/beegfs-mgmtd start bee-1-2$ yum install beegfs-meta bee-1-2$ /opt/beegfs/sbin/beegfs-setup-meta -p /mnt/vdb/meta2 -s 2 -m bee-1-1 bee-1-2$ /etc/init.d/beegfs-meta start bee-1-3$ yum install beegfs-storage bee-1-3$ /opt/beegfs/sbin/beegfs-setup-storage -p /mnt/vdc/storage3 -s 3 -i 301 -m bee-1-1 bee-1-3$ /etc/init.d/beegfs-storage start bee-1-4$ yum install beegfs-client beegfs-helperd beegfs-utils bee-1-1$ yum install kernel-devel gcc bee-1-4$ /etc/init.d/beegfs-client rebuild bee-1-4$ /opt/beegfs/sbin/beegfs-setup-client -m bee-1-1 bee-1-4$ /etc/init.d/beegfs-helperd start bee-1-4$ /etc/init.d/beegfs-client start bee-1-4$ echo 123 >> /mnt/beegfs/file.txt bee-1-4$ ls /mnt/beegfs

Hyper-converged Installation


Turn the nodes into non-dedicated servers following the hyper converged design, with BeeGFS mounted at /mnt/beegfs on all 4 nodes.
  1. Install the missing packages on each node and configure the BeeGFs services.
    bee-1-1$ yum install beegfs-meta beegfs-storage beegfs-client beegfs-helperd beegfs-utils bee-1-1$ /opt/beegfs/sbin/beegfs-setup-meta -p /mnt/vdb/meta1 -s 1 -m bee-1-1 bee-1-1$ /opt/beegfs/sbin/beegfs-setup-storage -p /mnt/vdc/storage1 -s 1 -i 101 -m bee-1-1 bee-1-1$ /etc/init.d/beegfs-meta start bee-1-1$ /etc/init.d/beegfs-storage start bee-1-1$ yum install kernel-devel gcc bee-1-1$ /etc/init.d/beegfs-client rebuild bee-1-1$ /opt/beegfs/sbin/beegfs-setup-client -m bee-1-1 bee-1-1$ /etc/init.d/beegfs-helperd start bee-1-1$ /etc/init.d/beegfs-client start bee-1-1$ ls /mnt/beegfs bee-1-2$ yum install beegfs-storage beegfs-client beegfs-helperd beegfs-utils bee-1-2$ /opt/beegfs/sbin/beegfs-setup-storage -p /mnt/vdc/storage2 -s 2 -i 201 -m bee-1-1 bee-1-2$ /etc/init.d/beegfs-storage start bee-1-2$ yum install kernel-devel gcc bee-1-2$ /etc/init.d/beegfs-client rebuild bee-1-2$ /opt/beegfs/sbin/beegfs-setup-client -m bee-1-1 bee-1-2$ /etc/init.d/beegfs-helperd start bee-1-2$ /etc/init.d/beegfs-client start bee-1-2$ ls /mnt/beegfs bee-1-3$ yum install beegfs-meta beegfs-client beegfs-helperd beegfs-utils bee-1-3$ /opt/beegfs/sbin/beegfs-setup-meta -p /mnt/vdb/meta3 -s 3 -m bee-1-1 bee-1-3$ /etc/init.d/beegfs-meta start bee-1-3$ yum install kernel-devel gcc bee-1-3$ /etc/init.d/beegfs-client rebuild bee-1-3$ /opt/beegfs/sbin/beegfs-setup-client -m bee-1-1 bee-1-3$ /etc/init.d/beegfs-helperd start bee-1-3$ /etc/init.d/beegfs-client start bee-1-3$ ls /mnt/beegfs bee-1-4$ yum install beegfs-meta beegfs-storage bee-1-4$ /opt/beegfs/sbin/beegfs-setup-meta -p /mnt/vda/meta4 -s 4 -m bee-1-1 bee-1-4$ /opt/beegfs/sbin/beegfs-setup-storage -p /mnt/vdc/storage4 -s 4 -i 401 -m bee-1-1 bee-1-4$ /etc/init.d/beegfs-meta start bee-1-4$ /etc/init.d/beegfs-storage start bee-1-4$ ls /mnt/beegfs
  2. Configure the management service to refuse the registration of new servers and targets, by editing its configuration file and setting the options below to false.
    $ vi /etc/beegfs/beegfs-mgmtd.conf ... sysAllowNewServers = true sysAllowNewTargets = true
  3. In addition, make sure that all storage, metadata and management services have the option below set to false in their respective configuration files, to prevent accidental initialization of unmounted target directories.
    $ vi /etc/beegfs/beegfs-meta.conf ... storeAllowFirstRunInit = false

Populate the System

  1. Create directories and subdirectories, from any machine.
    $ mkdir /mnt/beegfs/documents $ mkdir /mnt/beegfs/simulations $ mkdir /mnt/beegfs/simulations/2017 $ mkdir /mnt/beegfs/simulations/2018
  2. Create files of different sizes.
    $ echo "This is a data file" >> /mnt/beegfs/documents/report1.txt $ echo "This is a data file" >> /mnt/beegfs/documents/report2.txt $ dd if=/dev/urandom of=/mnt/beegfs/simulations/2017/file1.dat count=1024 bs=1024 $ dd if=/dev/urandom of=/mnt/beegfs/simulations/2017/file2.dat count=2048 bs=1024 $ dd if=/dev/urandom of=/mnt/beegfs/simulations/2018/results1.dat count=1024 bs=1024 $ dd if=/dev/urandom of=/mnt/beegfs/simulations/2018/results2.dat count=2048 bs=1024 $ ls -l /mnt/beegfs/simulations/2018 $ find /mnt/beegfs
  3. Create symbolic links.
    $ cd /mnt/beegfs/simulations/2017 $ ln –s file2.dat link2.dat $ ls -l $ cd /mnt/beegfs/simulations/2018 $ ln -s results1.dat link1.dat $ ls -l

Basic Commands Tests

  1. Check if all servers reachable from any machine.
    $ beegfs-check-servers Management ========== bee-1-1 [ID: 1]: reachable at 192.168.100.111:8008 (protocol: TCP) Metadata ========== bee-1-1 [ID: 1]: reachable at 192.168.100.111:8005 (protocol: TCP) bee-1-2 [ID: 2]: reachable at 192.168.100.112:8005 (protocol: TCP) bee-1-3 [ID: 3]: reachable at 192.168.100.113:8005 (protocol: TCP) bee-1-4 [ID: 4]: reachable at 192.168.100.114:8005 (protocol: TCP) Storage ========== bee-1-1 [ID: 1]: reachable at 192.168.100.111:8003 (protocol: TCP) bee-1-4 [ID: 2]: reachable at 192.168.100.114:8003 (protocol: TCP) bee-1-2 [ID: 3]: reachable at 192.168.100.112:8003 (protocol: TCP) bee-1-3 [ID: 4]: reachable at 192.168.100.113:8003 (protocol: TCP)
  2. Check if all client are reachable.
    $ beegfs-ctl --listnodes --nodetype=client --details 51C-5A254627-bee-1-1 [ID: 10] Ports: UDP: 8004; TCP: 0 Interfaces: eth0(TCP) 4B3-5A25460D-bee-1-2 [ID: 8] Ports: UDP: 8004; TCP: 0 Interfaces: eth0(TCP) 460-5A254617-bee-1-3 [ID: 9] Ports: UDP: 8004; TCP: 0 Interfaces: eth0(TCP) 3DA-5A25442A-bee-1-4 [ID: 5] Ports: UDP: 8004; TCP: 0 Interfaces: eth0(TCP) Number of nodes: 4
  3. List all metadata nodes and discover which version of BeeGFS each one using.
    $ beegfs-ctl --listnodes --nodetype=meta --nicdetails --showversion bee-1-1 [ID: 1] Version code: 6.17-0 Ports: UDP: 8005; TCP: 8005 Interfaces: + eth0[ip addr: 192.168.100.111; type: TCP] bee-1-2 [ID: 2] Version code: 6.17-0 Ports: UDP: 8005; TCP: 8005 Interfaces: + eth0[ip addr: 192.168.100.112; type: TCP] bee-1-3 [ID: 3] Version code: 6.17-0 Ports: UDP: 8005; TCP: 8005 Interfaces: + eth0[ip addr: 192.168.100.113; type: TCP] bee-1-4 [ID: 4] Version code: 6.17-0 Ports: UDP: 8005; TCP: 8005 Interfaces: + eth0[ip addr: 192.168.100.114; type: TCP] Number of nodes: 4 Root: 2
  4. List all store targets.
    $ beegfs-ctl --listnodes --nodetype=storage bee-1-1 [ID: 1] bee-1-2 [ID: 2] bee-1-3 [ID: 3] bee-1-4 [ID: 4]
  5. Check which storage target has more data at the moment.
    $ beegfs-df METADATA SERVERS: TargetID Pool Total Free % ITotal IFree % ======== ==== ===== ==== = ====== ===== = 1 low 14.6GiB 14.3GiB 98% 10.0M 9.9M 99% 2 low 14.6GiB 14.3GiB 98% 10.0M 9.9M 99% 3 low 14.6GiB 14.3GiB 98% 10.0M 9.9M 99% 4 low 17.0GiB 15.4GiB 91% 8.5M 8.4M 98% STORAGE TARGETS: TargetID Pool Total Free % ITotal IFree % ======== ==== ===== ==== = ====== ===== = 101 emergency 20.0GiB 18.7GiB 94% 10.0M 10.0M 100% 201 emergency 20.0GiB 18.7GiB 94% 10.0M 10.0M 100% 301 emergency 20.0GiB 18.7GiB 94% 10.0M 10.0M 100% 401 emergency 20.0GiB 18.7GiB 94% 10.0M 10.0M 100%

Reconfigure the System

  1. Redefine the storage capacity pool limits by editing the properties below in the management configuration file.
    $ vi /etc/beegfs/beegfs-mgmtd.conf ... tuneMetaDynamicPools = true tuneMetaInodesLowLimit = 5M tuneMetaInodesEmergencyLimit = 1M tuneMetaSpaceLowLimit = 100M tuneMetaSpaceEmergencyLimit = 50M tuneStorageDynamicPools = true tuneStorageInodesLowLimit = 5M tuneStorageInodesEmergencyLimit = 1M tuneStorageSpaceLowLimit = 100M tuneStorageSpaceEmergencyLimit = 50M
  2. Restart the management daemon and check run again.
    $ beegfs-df METADATA SERVERS: TargetID Pool Total Free % ITotal IFree % ======== ==== ===== ==== = ====== ===== = 1 normal 14.6GiB 14.3GiB 98% 10.0M 9.9M 99% 2 normal 14.6GiB 14.3GiB 98% 10.0M 9.9M 99% 3 normal 14.6GiB 14.3GiB 98% 10.0M 9.9M 99% 4 normal 14.6GiB 14.3GiB 98% 10.0M 9.9M 99% STORAGE TARGETS: TargetID Pool Total Free % ITotal IFree % ======== ==== ===== ==== = ====== ===== = 101 normal 20.0GiB 18.7GiB 94% 10.0M 10.0M 100% 201 normal 20.0GiB 18.7GiB 94% 10.0M 10.0M 100% 301 normal 20.0GiB 18.7GiB 94% 10.0M 10.0M 100% 401 normal 20.0GiB 18.7GiB 94% 10.0M 10.0M 100%
  3. Configure a subdirectory to stripe files across only 2 storage targets.
    $ beegfs-ctl --setpattern --numtargets=2 --chunksize=1m /mnt/beegfs/documents
  4. Create a file on that directory.
    $ dd if=/dev/urandom of=/mnt/beegfs/documents/report.doc count=2048 bs=1024
  5. Query which storage targets are being used to store the data of that file.
    $ beegfs-ctl --getentryinfo --verbose /mnt/beegfs/documents/report.doc Path: /documents/report.doc Mount: /mnt/beegfs EntryID: 0-5A5C9ADC-1 Metadata node: bee-1-1 [ID: 1] Stripe pattern details: + Type: RAID0 + Chunksize: 1M + Number of storage targets: desired: 2; actual: 2 + Storage targets: + 401 @ bee-1-4 [ID: 4] + 201 @ bee-1-2 [ID: 2] Chunk path: u0/5A5C/9/0-5A5C9642-2/0-5A5C9ADC-1 Dentry path: 59/16/0-5A5C9642-2/
  6. Raise the logging level of the client service by setting option in file and restarting the client services.
    $ vi /etc/beegfs/beegfs-client.conf ... logLevel = 4 ... $ /etc/init.d/beegfs-helperd restart $ /etc/init.d/beegfs-client restart
  7. Check if the log file contains any error message.
    $ less /var/log/beegfs-client.log
  8. Check the consistency of the file system.
    $ beegfs-ctl --listtargets --nodetype=meta --state TargetID Reachability Consistency NodeID ======== ============ =========== ====== 1 Online Good 1 2 Online Good 2 3 Online Good 3 4 Online Good 4 $ beegfs-ctl --listtargets --nodetype=storage --state TargetID Reachability Consistency NodeID ======== ============ =========== ====== 101 Online Good 1 201 Online Good 3 301 Online Good 2 401 Online Good 4 $ beegfs-fsck --checkfs --readonly ... Step 4: Check for errors... * Duplicated inode IDs ... * Duplicated chunks ... * Duplicated content directores ... * Bad target mirror information in dentry ... * Bad content mirror information in dir inode ... * Bad content mirror information in file inode ... * Malformed chunk ... * File has a missing target in stripe pattern ... * Dentry-by-ID file is present, but no corresponding dentry ... * Dentry-by-ID file is broken or missing ... * Chunk without an inode pointing to it (orphaned chunk) ... * Chunk is saved in wrong path ... * Wrong owner node saved in inode ... * Dentry points to inode on wrong node ... * Content directory without an inode ... * Dir inode without a dentry pointing to it (orphaned inode) ... * File inode without a dentry pointing to it (orphaned inode) ... * Dangling directory entry ... * Directory inode without a content directory ... * Attributes of file inode are wrong ... * Attributes of dir inode are wrong ... Found 0 errors. Detailed information can also be found in /var/log/beegfs-fsck.out.
  9. Measure the average throughput of the storage targets. Performance will be poor, because these are virtual machines.
    $ beegfs-ctl --storagebench --write --alltargets --size=1G --threads=2 $ beegfs-ctl --storagebench --status --alltargets Server benchmark status: Finished: 4 Write benchmark results: Min throughput: 14900 KiB/s nodeID: bee-2-1 [ID: 1], targetID: 101 Max throughput: 21989 KiB/s nodeID: bee-2-4 [ID: 4], targetID: 401 Avg throughput: 18517 KiB/s Aggregate throughput: 74071 KiB/s $ beegfs-ctl --storagebench --read --alltargets --size=1G --threads=2 $ beegfs-ctl --storagebench --status --alltargets Server benchmark status: Finished: 4 Read benchmark results: Min throughput: 14556 KiB/s nodeID: bee-1-1 [ID: 1], targetID: 101 Max throughput: 15346 KiB/s nodeID: bee-1-2 [ID: 2], targetID: 201 Avg throughput: 15102 KiB/s Aggregate throughput: 60408 KiB/s $ beegfs-ctl --storagebench --cleanup Cleanup storage benchmark folder. Server benchmark status: Finished: 4
  10. Discover which storage server is attending most requests while you use the system.
    bee-1-1$ dd if=/dev/urandom of=/mnt/beegfs/documents/report2.doc count=2048 bs=1024 bee-1-2$ beegfs-ctl --serverstats --nodetype=storage --perserver --names --interval=1 ... ===== time index: 1516021894 ===== nodeID write_KiB read_KiB reqs qlen bsy name 1 0 0 1 0 0 bee-1-1 2 2048 0 9 0 0 bee-1-2 3 2048 0 9 0 0 bee-1-3 4 0 0 1 0 0 bee-1-4 ===== time index: 1516021895 ===== nodeID write_KiB read_KiB reqs qlen bsy name 1 0 0 1 0 0 bee-1-1 2 1024 0 5 0 0 bee-1-2 3 2048 0 9 0 0 bee-1-3 4 0 0 1 0 0 bee-1-4 ...

Mirroring Enabling

  1. Enable metadata mirroring.
    $ beegfs-ctl --mirrormd Operation succeeded.
  2. Enable storage mirroring for some directories.
    $ mkdir /mnt/beegfs/mirrored $ beegfs-ctl --setpattern --chunksize=1m --numtargets=2 --buddymirror /mnt/beegfs/mirrored New chunksize: 1048576 New number of storage targets: 2 Path: /mirrored Mount: /mnt/beegfs

Failover Tests

  • Create a new file in the mirror directory and check if it is really mirrored.
    $ dd if=/dev/urandom of=/mnt/beegfs/mirrored/file.dat count=2048 bs=1024 $ beegfs-ctl --getentryinfo --verbose /mnt/beegfs/mirrored/file.dat Path: /mirrored/file.dat Mount: /mnt/beegfs EntryID: 1-5A5CB326-2 Metadata buddy group: 100 Current primary metadata node: bee-1-2 [ID: 2] Stripe pattern details: + Type: Buddy Mirror + Chunksize: 1M + Number of storage targets: desired: 2; actual: 2 + Storage mirror buddy groups: + 200 + 400 Chunk path: u0/5A5C/B/0-5A5CB326-2/1-5A5CB326-2 Dentry path: 67/3E/0-5A5CB326-2/
  • Stop and in servers of different groups, e.g.: bee-1-2 and beegfs-1-4.
    bee-1-2 $ /etc/init.d/beegfs-storage stop bee-1-2 $ /etc/init.d/beegfs-meta stop bee-1-4 $ /etc/init.d/beegfs-storage stop bee-1-4 $ /etc/init.d/beegfs-meta stop
  • Check the roles of the targets and try to read the files after the remaining targets become primary in their mirror groups.
    $ beegfs-ctl --listmirrorgroups --nodetype=meta BuddyGroupID PrimaryNodeID SecondaryNodeID ============ ============= =============== 100 1 2 200 3 4 $ beegfs-ctl --listmirrorgroups --nodetype=storage BuddyGroupID PrimaryTargetID SecondaryTargetID ============ =============== ================= 100 101 201 200 301 401 $ dd if=/mnt/beegfs/mirrored/file.dat of=/tmp/trash count=2048 bs=1024


Homework 3

BeeOND Installation

    • Authorize the user to log in to the other machines using its local RSA key.
      $ ssh-copy-id root@bee-1-1 $ ssh-copy-id root@bee-1-2 $ ssh-copy-id root@bee-1-3 $ ssh-copy-id root@bee-1-4
    • On one of the nodes, create the containing the hostnames of all 4 nodes.
      bee-1-1 $ echo bee-1-1 > nodefile bee-1-1 $ echo bee-1-2 >> nodefile bee-1-1 $ echo bee-1-3 >> nodefile bee-1-1 $ echo bee-1-4 >> nodefile
    • Start BeeOND.
      $ beeond start -n nodefile -d /mnt/vdb/beeond -c /mnt/beeond

BeeGFS Commands Tests

  1. Use BeeGFS commands on the BeeOND system.
